A bird is sitting in a large closed cage which is placed on a spring balance. It records a weight of 25 N. The bird (mass=0.5 kg) flies upward in the cage with an acceleration of 2m//s^(2) . The spring balance will now record a weight of :-

A bird is flying in a wire cage hung from a spring balance. Reading R_1 of the spring balance is recorded in this case. Reading R_2 is taken when the bird sits at rest in the case. The R_1 will be

The apparent weight of the body, when it is travelling upwards with an acceleration of 2m//s^(2) and mass is 10 kg , will be

A spring balance is attached to the ceiling of a lift. A man hangs his bag on the spring and the spring reads 49 N, when the lift is stationary. If the lift moves downward with an acceleration of 5 m//s^(2) , the reading of the spring balance will be :

A body of mass 50 kg is hung by a spring balance in a lift. Calculate the reading of the balance when : The lift is ascending with an acceleration of 2m//s^(2) .
